Product details
PTH804SAll stainless steel high-precision differential pressure sensor/transmitterIt is assembled using pure imported (American SMI5651) differential pressure chips, with on-site display function, making it convenient for users to view data in real time. The shell is made of 304 stainless steel structure. The two pressure interfaces are of a Ø 8 tower head structure, which can be directly installed on the measuring pipeline or connected through a pressure pipe. Widely used in the fields of boiler air supply, building fire protection, leak detection machinery, underground ventilation, and pressure process control in the power and coal industries.
